Synthesis, Photophysical, Electrochemical, and Quantum Chemical Properties of Cationic Iridium Complexes with Oxadiazole based Ancillary Ligand. |
| 초록 |
We report the synthesis and characterization of the cationic iridium complexes [Ir(ppy)2(mpoxd)]PF6 (1), [Ir(dfppy)2(mpoxd)]PF6 (2), [Ir(piq)2(mpoxd)]PF6 (3), and [Ir(pq)2(mpoxd)]PF6 (4). UV–visible absorption spectra, photoluminescence (PL) emission spectra, and cyclic voltammetric measurements were obtained to explore the photophysical and electrochemical properties. The significant blue shift in the emission spectrum of 2 is due to the presence of electron-withdrawing fluorine atoms on Hdfppy, which stabilizes the highest occupied molecular orbital (HOMO) to a greater extent than in the other complexes. The electrochemical and photophysical properties of the complexes were also calculated using density functional theory. The results indicate that the optical properties of the complexes can be effectively tuned by selective design of the cyclometalating and ancillary ligands. |
